Red Trinket <<<<< Mass Ward. Intentional?
No matter how many wards you sweep, the enemy's always going to just plant another one right where you swept a few seconds later. Or they'll have too many that are spread out, and you simply cannot clear them all, making that Baron bait impossible.
"Tell your team to get mass red trinkets!"
Complete suicide. Yellow trinkets are kind of a requirement, otherwise you'll always be marching in blind.
"Use Oracle's Lens!"
Still not effective enough. Like I said, wards are INFINITE. Oracles can be baited, and you generally only get it for anti-stealth. If you do, you can't use it to sweep for wards. How will you detect that Vayne if you do?
What I'd really like to know is if this whole "mass ward beats red trinket" mentality was intended from the start. Pro players might use it well, but how do the rest of us handle an area with 8-10 wards in it?
